Lens Control

[Jiri Bakala]

When the camera is used with an EFP/ENG type of lens that includes zoom rocker, start/stop button and other electronic controls, is there any way of plugging the standard lens (Fujinon/Canon, etc.) connector to the camera? If yes, would there be full funcionality?

 

[Martin Drew]

There is a lens connector which will bring power to the lens and accept the start/stop control. The automatic iris won't work though because there is no iris control from the camera. Zoom rocker will work fine and any demand plugged into the lens should work too. So there won't be full functionality, but the lack of auto iris shouldn't be a huge issue for most applications.

I posted this elsewhere but it's worth repeating on this specific thread:

"I'd also LOVE to see the option of a servo-controlled zoom lens for RED that doesn't require stepping down to a 2/3" B4 HD broadcast lens (plus a $4000+ optical adapter) and the resultant loss of resolution that produces (limitation of no greater than 1080P, loss of more than 2 stops in aperture).

Documentary shooters want the option of getting the full blast of the Mysterium Sensor too... but they can't have somebody running alongside to pull focus as they manually zoom a 35mm lens while trying point in the right direction as they chase after the unscripted chaos of the real world!"

Having a good servo-controlled lens available for RED that would allow for full 4K shooting sure would help make it as universal and it could/should be!

LOL, good point.

That was Awesome!:biggrin:

You could of course mount a zoom motor on a geared lens and use a controller like a microforce mounted on to RedRails. That would give you servo zoom. And it wouldn't be as kludgy as my description probably sounds. Oppenheimer do a holder for the Microforce to allow you to do this. Visual Products have a second hand one listed: http://www.visualproducts.com/storeProductDetail02.asp?productID=885&Cat=3&Cat2=45

Thanks for the suggestion Martin.

A set-up like that would really slow you down when you need to change lenses wouldn't it? It appears a lot of fiddling would be required. I also worry about the durability and reliability of such a set-up when you're shooting docos "in the wild". I'd need to look further into the whole idea before making any final judgment.

The other thing is, most doco camera men are used to operating Canon/Fujinon lenses with the good old "rocker" and I'm sure they'd operate the lens better if the servo control was in it's normal place. Like riding a bike, their '"zoom-hand thinking" has moved out of the cerebral cortex and into the brain stem!

Zoom on lenses

Zoom on lenses

Each to his own taste?

Reality is that at this time there are no 35mm lenses with zoom / rocker switches on them, only 2/3" B4 mount lenses.

So the two options are - place motors and an external actuator (like a Preston micro-force) onto a P/L mount cinema lens, or use an optical adaptor with a 2/3" B4 lens - which effectively limits you to 2K - but that's still better image resolution than 2/3" HD cameras.

As potential customers, your input to Canon and Fujinon, Cooke and Zeiss would be the best path forward if either of the above don't appeal. I honestly think though that most people will be pretty happy with the performance and convenience that they will get from either of the first two options.

 

[Brainstorm]

Thanks for your input Stuart. At least I can now be sure that these are the only two options and do the necessary investigation to work out which solution is best for the type of productions I'd like to use a RED on.

1. Stuart does the RED basic body have the cool little rosette on the side which allows the mounting of the Oppenheimer handle as shown in the picture? Cage seems a little self defeating here for a doco guy? Also the use of the micro-force is a way different feel from the rocker, my feeling is that the Oppy part works much better on the pan handle.

2. Brainstorm. My HD lens in B mount is about 20X 2/3" In super 16 size with the windowed sensor and Abakus 132 I can shoot 2K in Doco. mode. Also I can use the doubler when needed. This is equivalent to a 40 to one 35mm zoom. There is just no optical way in heck that you can carry something like that even if it was available! Yes I know a doubler between the body and the lens, but everything will have changed while you change the lens off to put it in. The quick lever doubler is really handy so many times in Doc. work.

Also remember we are pulling focus ourselves by eye. On 4K with 35m lens wide open... eh eh

The adapter in the S16mm size Abakus 132 is $3000 us. The $4000 adapter model 260 would adapt you to 35mm. So then you could use the 4K sensor, and your B4 lens, at the price of only 4K and some serious focus issues. I also think most of the HD lenses out there will show some quality issues when stretched over 4K on a 35mm size sensor. This needs a test! There have though been quality issues you could see in HD1080!

Exactly what I've just been by the local lens experts here in Sydney TJ. They're really excited by RED's specs, but they also say that until some new type of servo-driven HD lens that covers the area of the sensor is put on the market, RED (or any other equivalent) may not the best (and most cost-effective) option for shooting low-medium-budget indy cinema-docos that require "everyday" zoom control. I wish they were wrong, but I fear they are right. I know that RED is extraordinary value for what it offers, but the other bits needed to complete the system aren't: e.g. A Microforce zoom control system costs about 12-13 thousand $ here... then you still need to buy the lenses. If you go for a PL-B4 adapter, you can add another 5-6 grand plus a 2/3" B4 lens or two, then there are the rails, the cage, the cases, the data back-up system, the NLE machines to cut and handle 4K/2K data, etc, etc, etc.

It all starts adding up when you're working on a budget that's meant to be "low"!

Curt v. Badinski of Viewfactor Studios, who´s a regular poster here told me that their new LCS will be released at NAB this year - and if I understand, their 3 channel system comes at 3500 dollars.

 

[Martin Drew]

Are you sure Kalone. I seem to remember that Curt was pitching that at $5500 for the 3 channel and $3500 was for a single channel (still excellent VFM). If it is $3500 for 3 channels that will be stunning!

It depends what you are comparing it with. It is very tempting to see RedOne as only applicable to full on 4k film style production and then thinking in terms of the ancillary equipment costs necessary to achieve that. If instead you eschew 4k, opt for a B4 mount lens + adapter, then shoot and edit 2k the camera + kit will be far cheaper than an equivalent 2/3" XDCAM solution (which would be lower resolution and lower quality). There are other issues which might make XDCAM (for example) more appropriate to you but it isn't going to be down to cost.

Of course if you want to shoot and edit 4k and you want to have higher production values which requires more extensive grip then that is going to get expensive, but that is true whatever format you shoot. I don't think it is relevant to compare the cost of a B4 mount eng/efp lens + servo with a 4k appropriate lens + lens control. Look at the total system cost to achieve the same result as whatever other system you are considering.

Yes, we are going to be at NAB... you'll have to wait until then for more info

Such a tease Curt :biggrin:

Hi Martin,

All the production values in the world don't make it any easier to raise finance for a "low-medium budget" doco. As well all know, getting any "risky" film funded is an uphill battle. I agree that RED is (theoretically) way ahead of the competition in a $ for $ shootout, but it's still not cheap by the time you add all the necessary equipment required to shoot and post-produce.

One of the local cine-hire places here in Sydney (they rent everything from Genesis, Vipers, Varicams and XDCams, plus everything else that goes with them) is watching RED with great interest, but they still reckon it will cost close to $100K to get a full RED system ready for a shoot here in Australia. That's well beyond the budget of most small indy doco makers who are trying to make their films on the smell of an oily rag.

Cheers
Brainstorm


P.S. I should add to my comments: I REALLY want RED to work for the sort of doco work I do! I'm very excited by this camera's potential and totally support Jim Jannard's team's extraordinary innovation. (I've also enjoyed wearing Oakley sunglasses and specs for years. Hell. I even had Oakley grips on my motocross bike when I was a kid!) I just have to find an affordable way to be able to use a RED on shoots where travelling with a focus puller is not an option. The camera is not the problem. It's the lack of (affordable) servo-zoomable 35mm lenses that's the issue for me.

I didn't know Microforces were THAT much. Not to mock your post (or anyone with a REAL need for motorized zoom lenses), but doesn't that just "force" (most) of us shooting narrative drama to just shoot with fixed primes with lotsa ultra-cool dolly shots? For cinema purists, at least, the motorized zoom shot is by far the least "cinematic" anyway, yes?

 

[Ralph Oshiro]

Sorry, Brainstorm . . . just re-read your post! Certainly, documentary work would surely benefit from a motorized zoom lens. Surely, Microforce can't be the only game in town?

I think you're missing the point of my post. Sure you can spend a lot of money on a RedOne dream kit but you don't have to, you can "cut according to your cloth" that is what is so exciting about this camera. The body is so cheap that even if you add on the price of a b4 to PL adapter it will still cost you less than most other low low end professional kit. Sure you will still have to buy B4 lenses but that is true whatever camera you buy. It sound like you are arguing that even though the body is cheap the price of the total package will be "high end", but that doesn't have to be the case. What is your budget for camera + lens? what alternatives to RedOne are you considering? maybe that would make it easier, we could actually put figures to all this and compare the options. You spoke about having to buy a NLE that can handle 4K/2K, do you need 4K? very few top end feature films go through a 4K scan let alone print at the moment. For editing you would probably want to use standard definition anyway.



Ralph

There are many options other than the microforce for zoom control, you could look at the Bar-Tech Buz which allows you to interface a conventional video zoom demand to a lens zoom motor. Also I saw a Cinema Products J-6 controller + motor on eBay recently which went for $500, but I would wait to see what Curt is going to announce at NAB, that sounds very interesting.
